"It's always disappointing to lose but that was tough to take being up by 10 with not too long to go but again it's the same old story," Sharp said.

"They're trying their socks off and they're trying really hard but just things aren't happening, making errors at vital times and that's about the bottom line."

Sharks captain Paul Gallen said vice-captain Wade Graham had not made an official complaint after the game following his accusation that Tigers winger David Nofoaluma bit him midway through the first half.

"I don't know, I wasn't in the tackle. Nothing happened. Wade didn't make a complaint so there's nothing in it as far as I'm concerned," Gallen said.

"The penalty was a bit tough. I mean a little tap on the head. It is footy so probably shouldn't have been a penalty but there was nothing in it."
